Zone insulation
RCD with no visible crack — megohmmeter on the heater before ordering glass.

Cooktop repair in Sergeli-5: a zone blinks or the panel RCD trips — we test the coil and insulation, then work after the estimate.
On Hansa and Whirlpool in older mid-massiv kitchens the RCD more often means damp insulation, not cracked glass.
Sergeli-5: the board sits in the panel entrance — we kill the hob breaker on site and do not name invented streets.

How the visit works
RCD with no visible crack — megohmmeter on the heater before ordering glass.
All zones blink — hob line filter, not the coils at once.
Heat is gone, lamp stays — residual sensor after probing.
Topic 1 / 4
If a burner won't light, the flame is weak, or you smell gas — don't use the hob. The technician checks nozzles, ignition, the gas valve and connection seals.
If a leak is found, we fix the cause first, then run a test ignition. We explain the scope of work and agree on the price before repair starts.
Tell us the model and symptoms — we'll advise on a home visit and prepare for diagnostics.
